Hello, forum
My Nexus 7 3G has been showing some battery issues lately. A while ago, the device was on airplane mode with WiFi connected. The only running apps were Temple Run 2 on the background and Whatsapp. The battery got down to 2% when I noticed it so I plugged it in with the original 2Amp charger and the original short cable. After around 5 minutes, the battery went down to 1%, and then the device died. Now, it's still plugged in. When I try to power it on, it shows the charging screen (first with the battery with the charge icon and then a battery with in a filling up cycle. After 5 cycles, the screen goes blank. There is no other response from the device. Please help.
Thanks in advance.
Regards
Raptor
UPDATE: Okay, I think I fixed it. While the charging icon was on the screen, I pressed the power button again till it booted up. The battery was at 9% on boot, so it was charging fine. Still, that behaviour is unusual.

So the phone was really low, at 6% this morning. SO I put it on the wall charger. I saw the icon come up that it was charging and then put the phone down.
A while later I went back to the phone and saw that although the charger was plugged in to the wall and also plugged into the phone, it was NOT charging.
Using the phone I went to my contacts to check a phone number and then it turned off, due to no charge.
I plug it into the wall charger, the USB connected to the computer, as well as the car charger and here is what happens:
The top and bottom of the phone blink red for about 1-3 minutes.
Without pressing anything on the phone it automatically turns itself on, I see the Sony Ericsson boot screen, the Windows boot screen then my SPB Mobil Shell screen for about a second and then it turns off again showing and the blinking red light for about 1-3 minutes and then it starts the process all over again.
I think that a setting for Backlight/Power management was changed. As setting similar to "Only charge with usb", or "only charge when connected with ActiveSync" or somthing like that.
The problem is that I turned off the Active sync on the phone in order to conserve battery power so that I could look up the phone number from my contacts. And after I did that the phone shut off and I cannot change it, because it will not charge.
I do not have a different, charged, battery to try and do not think that I can find one easily.
Any suggestions?
Now when I see that the phone is re-booting(I see the SE logo), I use the stylus to to soft reset. It is obvious that there is some type of charge happening before it re-boots, , otherwise it would not re-boot. SO my theory is that by doing a soft rest between restarts, the battery will gain more of a charge each time. And possibly have enough of a charge so that I can go into my settings and see the backlight/ power settings have been changed.
So I took a battery from my old SE 902 phone and rigged it to work with my X2.
It booted up just fine. I was able to get into the menu for power settings. Nothig was changed however I did check the box "do not charge when connected to the computer" backed out of that screen and then went back into the screen and unchecked the box.
I powered down the phone and the screen went to the default charging battery meter.
I then put the proper battery in the phone and it was still blinking red. I saw it blink green for a few seconds, then I felt it vibrate, and then I saw the green battery meter. But after a few seconds it went back to blinking red and I could not see the battery meter again.
This seems to be happening intermittenly. As of right now there is a green blinking light and I see a dimmed battery meter.
Hopefully it will be fine, we shall see.
So it was charging for a while and now has stopped. I see the battery meeter, but there is no green bar moving up. and the light has stopped blinking.
I unplugged the usb and I still see the battery meter with no green bar moving. Installed the back cover and plugged the usb back in.
Now it is back to the red blinking again. . . ? ? ? ? ?
I think that it is a battery issue.
CAn anyone suggest why a battery would all of a sudden stop working?
Just ordered a new battery. $70.00!!! Ouch!!!
It does come with a battery charger for use with a Mini USB, but still, $70.00 is a lot of money!!
I will update with the results after i charge it up.
I got the new battery and put it into the charger. As I mentioned in an earlier post the new battery came with a separate charger for use with a mini usb. At first I had problems. The charger would not charge the new battery. I was using a wall connected mini usb to power the charger. So I went to the computer and tried the mini usb from there. It still would not charge. So I took the battery out of the charger and put it into then phone and went back to the wall charger and it was charging. I could feel the phone vibrate and then saw the battery meter slowly fill with green and back to empty and then fill green again.
So I decided to do a few other chores around the house and went to check the charging status after about 10 minutes. I noticed that the phone was on!! I did not turn the phone on. No one else was in the house to turn it on. It was just on. Weird.
So I took the battery out of the phone and decided to try the new charger again with the computer mini USB. It WAS charging this time!! I charged the new battery on this charger using the computer mini USB until the red light(charging) turned green (finished charging) and then put it in the phone. It works fine.
I then decided to put the defective battery into this charger and it was actually charging!! I left it overnight and it was green this morning: identifying it as a full charge.
When the new battery is down to 10% or less I will take it out and put the defective battery in and see what happens.
So I put the original battery back in after the green light came on identifying a full charge on the accessory charger.
It showed 1% and a message came up identifying that "the battery is low, please charge asap", something like that.
So, in my unprofessional opinion , the original battery is toast.
The new battery worked great after its initial charge using the included accessory charger.
When I decided to charge it using the phone itself with the wall charger I noticed some really weird things happening.
First of all you should know that I downloaded and installed Spoon Charge. Look it up here on the forums, free and works great. It basically tells you what charge level you have, temperature of the battery, what voltage is coming in to charge it and also type of charge the battery is doing: trickle, fast, very fast and on battery.You can set it to read reading at specific time intervals: I have it set to read at every second.
I noticed that the charge kept bouncing between very fast and trickle. At one point it went to on battery, then to trickle then to on battery then to fast.
Ok. Weird. . . I thought to myself.
So I let it continue to charge overnight.
The next day I "tried" to use the phone. it was as slow as it was at it's factory installed settings before I did the memory card fix, accelerator settings, and other fixes that I forgot now have forgotten that I have installed.
At this point I decided to drain the battery as fast as I could by turning on WiFi, Bluetooth, and play a movie at the loudest volume possible. As soon as it reached 10% I took the battery out and charged it with the accessory charger. The next morning I saw that the indicator light was green showing full charge and installed the battery in the phone. It booted up and I immediately received a message that the battery was low, saw 1%.
Knowing that this was a BRAND NEW BATTERY, I turned off the phone and took the battery out and waited a few seconds until I put it back in and rebooted the phone.
This time it said 86% charge!!!!!!
WTF!!!!
So I tried to use the phone and it was as sluggish as before. After about 25 minutes it was starting to be a bit faster but nothing like it was before.
I am really confused now. Since I have a new battery I have ruled out that as a problem. So now is it the phone itself? Could it be the wall charger that is faulty?
Any other suggestions would be greatly appreciated.
Another update.
I put the original battery in the phone and now it works!!!! The old battery that would not charge now charges and works!!!
The phone is not the same. Still really slow, can't get it out of the "LOCKED" position when I want to answer a phone call. Opera is sliggish then fast then sluggish. Not what I had the phone at before all of this started. It actually WAS stable. It WAS useable. Now I want to throw it into the drink!!!!!!
Not sure what to think anymore.
well bro go into the system help of ur mobile press as i say
2ce the end button one time call button, 2ce the end button one time call button,one time end button and u will find the problem it is in the charging port the same issue with me
Hello! i have problem with my streak 5, few days ago battery drained out and phone shut down.
i connected ti a charger but nothing happen, no reaction on phone so i left it on charge all night.
Still no response, no picture on the screen, no backlight, no LED, completely dead.
I can get reaction only when i enter in fastboot mode (holding power+camera)
IN this mode touch screen not working, computer recognize device and i can do flash and i do it successfuly but i still cant turn on my phone.
What can be a problem, I tried everything with no luck, also i have not found anyone with same problem
I have 2.2 official, no root.
Try changing the battery. The one you have could be defective, or else there is an issue with the charging circuit.
I measured with instrument 3,67V, connected od 1 and 4. And few other combination i get from 3,30 to max 3,67V.
This seem to be ok, regardless of that you think might be the battery?
Never let the battery drain that much becase now the battery doens't have enough power to start the charging... you should charge the battery manual with some wires on (+) and (-) from a old phone charger be carefull with the voltage(V) and the ampers(A) not to brake the battery, 20 or 30 min should be enough, or you should buy one of this Universal charger. Then place the battery in the phone and it should work ok .
This morning I optimistically tried to turn on a phone and it was successful
battery Indicator showing 7% so i connected to charger, now is normaly charging, everything is working normally...
I do not understand, what could happen? i few times drained battery to 0% but still able to charge, maybe battery is problem, but again, turned on after 3 days
Don't worry the battery is ok the problem is not to empty it again to 0%, at 5% 7% close the phone if you don't have a charger to charge it. This method applies to every phone and battery. It's not a good thing to fully discharge.
Now is fully charged and power is 4,07V.
So obviously battery caused this problem.
I think, good info for all who suspect on battery, 4,07 V is power you need to have on fully charged battery.
With 3,6V you cant event turn on the phone.
Thank you for suggestions
Hi,
I've a strange problem with my N7. Today it completely turned off because the battery was 0%. As I noticed that I plugged it in to charge. Since then it continuously reboots but doesn't charge at all. I'm still stuck at 0% battery.
I tried different mUSB cables but that did not help.
When it reboots, I can see the lockscreen with the info that the device is charging but after a few seconds it just turns off (without the notification "Device shuts down" or sth like that).
I also noticed a buzzing sound while the N7 is plugged in....
Ok, good news. After another restart I quickly activated the airplane mode and after one reboot it finally showed 2% battery. I have no idea why it charges with airplane mode one, but I am that's back alive...
Finally receieved my Nexus 4 after almost 2 months waiting, but not really enjoying it right now.
Received it yesterday, unpacked it and I couldn't turn on the phone. So I've connected the cable into the charger and a light showed up.. After 30 min I saw a battery icon and after 1 hour I could turn up the phone.
When turned on, it showed 3% battery, so I let it charge for about 5 hours. While charging I've noticed something strange.. it was charging very slow. After 4h of charging it was showing just 16% battery and 1h later it was suddenly at 70%. After it got till 99% I unplugged the charger and tried to use the phone.
Everything worked till I wanted to restart it. The phone doesn't want to start up! Pressing the powerbutton for 20-30 seconds.. nothing happens. Tried the volume button combination.. nothing. Plugged it into my PC and after 10 min the battery icon showed up?! The battery was at 0%! The battery went from 99% to 0% just by turning it off!
I've let the phone charge again, this time the whole night (7 hours).. It was fully charged at 100%. I disconnected the charger and turned off the phone.. and again: a black screen.
I've Googled and searched everywhere but couldn't find 1 thing.. what could be the problem of this? How can my phone go from 100% to 0% by turning it off?
I have no idea what is going on but you need to contact google asap, they'll send a replacement and hopefully the new one isn't a dud.
If you want to try playing with it, plug the phone into a different charger with a different cable, let it charge overnight/12hrs and give it another shot it could be a bad cable/charger (to be honest I think this is a long shot.)
Really sounds like a hardware problem.
Your only option is RMA.
I got my nexus 4 on Tuesday morning, plugged it in to the charger, waited until it reached 100%, then inserted my sim card, turned it on, upgraded through OTA from 4.2 to 4.2.2 and then set up my usual things. I discharged the battery from 100% to 16%, then I turned it off and plugged to the charger. I turned it on when it was at 95%, and unplugged from the charger because I had to get out of home. This morning it was roughly at 30%, then I turned it off and plugged it to the charger. Later I turned it on, it was at 93%, so I waited until 100% before unplugging. It stood ages at 99%, so I turned it off. A little bit later I tried to turn it on, and when I pushed the power button it showed that the battery was charged, then the image disappeared and the led began blinking in red until I released the power button. I unplugged it, then powered on, and it booted, everything as normal: but the battery was on 94%. I plugged it in and after one minute it was already at 99%. I turned it off, then pressed the power button, but same behaviour: image, then red led blinking. So I plugged the phone to my galaxy nexus charger, waited for a little, and then same behaviour again. So I unplugged it, turned it on, and when I was in the system I saw that the battery was on 100%.
Now the battery is normally discharging while using it, no strange values.
What should I do now? Should I let it discharge until it turns off, or should I never let it discharge until it turns off? And should I charge it with the stock charger or the galaxy nexus charger? I'll be grateful to everyone makes me know what he thinks.
Excuse me for my poor English and for how much I wrote, I would make things clear as possible.

I am sorry for my lazy, I only skim through your post, but I do read the question.
I read somewhere in this 4rum that the Nexus4's battery can be charged at anytime you want.
FOr me, I usually use the phone until 20-30%, then I turn my phone off and charge.
For my brother, he charge without any pattern, and he doesn't turn the phone off when charging.
For my own opinion, you shouldn't use the phone until the batter is empty.
Notice the same thing 3 times with my Nexus. Have searched for a answer to this but no one has a answer I guess or just ignore it. I just power up without it being plug in ..
R: My nexus 4 refuses to turn on while attached to the charger
Now it's at 13%, i'll plug it in the next 10 minutes, then i'll see what will happen this time. Very strange indeed.. I'm only a little bit scared about the "red led death" i read about here and there over the internet.

I never turn mine off. I charge it all night every night when I sleep. Stays on.
Send it back? Rma?
as above i charge my device every night, its never powered off,. is the device hot while charging not like usual warm temp, but very hot that the device detects an issue?
the battery stats are wiped each time its charged, i guess you have some internal failure, battery not being detected after you disconnect from mains or reported as flat, faulty, unreliable source
its best not to fully discharge the battery but maybe you should use it till it powers off then recharge, any charger is fine, but you dont need anything higher than 1amp
i would return it, would suck to have an issue away from home.
